REV 66526-20130930 8
66526 ENGLISH
ASSEMBLY
Add Fuel Cont’d.
Our engines work well with 10% or less ethanol blend
fuels. When using blended fuels there are some issues
worth noting:
– Ethanol-gasoline blends can absorb more water than
gasoline alone.
– These blends can eventually separate, leaving water or
a watery goo in the tank, fuel valve and carburetor.
– With gravity-fed fuel supplies, this compromised fuel
can be drawn into the carburetor and cause damage to
the engine and/or potential hazards.
– There are only a few suppliers of fuel stabilizer that are
formulated to work with ethanol blend fuels.
– Any damages or hazards caused by using improper
fuel, improperly stored fuel, and/or improperly
formulated stabilizers, are not covered by
manufacture’s warranty.
It is advisable to always shut off the fuel supply, run the
engine to fuel starvation and drain the tank when the
equipment is not in use for more than 30 days.
NOTE
Use regular unleaded gasoline with a minimum
octane rating of 85.
Do not mix oil and gasoline.
Fill tank to approximately ¼ in. (0.64 cm) below
the top of the tank to allow for fuel expansion.
DO NOT pump gas directly into the chemical pump
at the gas station. Use an approved container to
transfer the fuel to the chemical pump.
DO NOT fill fuel tank indoors.
DO NOT fill fuel tank when the engine is running or hot.
DO NOT overfill the fuel tank.
DO NOT light cigarettes or smoke when filling the
fuel tank.
CAUTION
Connecting Hose or Pipes
Hoses or pipes can be connected to the pump using
2 in. (5 cm) NPT pipe fittings.
Teflon tape is required to ensure a liquid tight seal.
Do not connect rigid pipe directly to the pump as this
can cause excess stress that can damage the pump.
Always use at least 12 in. (30.5 cm) of flexible hose
between the pump and any rigid piping.
9 REV 66526-20130930
ENGLISH 66526
Chemical Pump Location
Place the chemical pump in a well ventilated area. DO
NOT place the chemical pump near vents or intakes
where exhaust fumes could be drawn into occupied
or confined spaces. Carefully consider wind and air
currents when positioning chemical pump.
This chemical pump must have at least 5 ft. (1.5 m) of
clearance from combustible material. Leave at least
3 ft. (0.91 m) of clearance on all sides of the chemical
pump to allow for adequate cooling, maintenance and
servicing.
Place the pump on a level surface free from any
obstructions or potential hazards. The pump should be
placed close to the water or chemical level to ensure
maximum pump performance.
Liquids Only - This pump may be used to transfer
and pump a variety of chemicals and certain other
substances including water, but they all must be liquid
form only. This pump is not meant to have any solids,
debris or trash, pass through or pumped through it.
This will damage the pump. Please only pump liquid
materials. A strainer or filter is always recommended for
use when pumping, as this may help catch any solids
that may otherwise pass through and damage the pump.
Chemicals - This pump may be used to pump certain
chemicals, but must follow any warnings, cautions and
directions for that specific chemical(s). Certain chemical
can be and are hazardous. They must be handled with
care and caution at all times. Follow all local and federal
laws for any and all chemicals. DO NOT mix chemicals.
Flushing the pump with water after using chemicals is
recommended.
Pump output will be affected by the type, length, and
size of the suction and discharge hoses. The pumping
height, also known as the total head, is the distance
from the water level to the point of discharge. As
this distance increases, pump output decreases. The
discharge capacity is greater than the suction capacity.
Therefore, it is important that the suction head is less
than the discharge head.
The time required to draw water or chemicals from the
source to the pump (self-priming time) can be decreased
by minimizing the suction head.
OPERATION
Flush the pump after every use. Flushing the pump,
pipes and hose kits with water will only help to
reduce the residue build up of materials, chemicals,
and pesticide used and may not flush out the
pump, pipes and hose kits completely.
NOTE
DO NOT run the pump dry.
Running the pump dry can destroy the pump seals
and will void the warranty. If the pump was running
while dry, stop the engine and allow it to cool
thoroughly before filling the chamber with water.
WARNING
TOTAL HEAD
DISCHARGE HEAD
SUCTION HEAD
ONLY liquid materials, chemicals and pesticides
are for use with this pump. Dry, solid or aerosolized
materials, chemicals and pesticides are not to be
used with this pump. Fumigants of any kind are not to
be used with this pump.
WARNING
Once certain materials, chemicals or pesticides are
used with the pump it is recommended that the
pump is not used to water plants, trees, crops, live
stock, or any other living creatures as certain material,
chemicals and pesticides residue may remain in pump
and be pumped through with any water or other liquid.
This may cause serious harm to or even kill any plant
life, crops, livestock or other living creatures.

Pesticides - This pump may be used to pump certain
pesticides, but must follow any warnings, cautions and
directions for that specific pesticide(s). Pesticides are
hazardous chemicals that must be handled with care
and caution at all times. Pesticides are regulated by
the United States Environmental Protection Agency
(EPA) and should follow any and all EPA guidelines for
proper and safe use. It is recommended that both the
specific pesticide guidelines and the United States EPA
guidelines be followed at all times.
Pesticides may leave residue in the pump and any
pipes or hose kits attached to the pump, so after
each pesticide use, flushing the pump with water is
recommended. If this pump is used to pump/spray any
other non-flammable liquids and/or chemicals please
keep in mind, residue from pesticides may also be
pumped too.

ENGLISH 66526
OPERATION
Operation using the alternative main jet at
elevations lower than the recommended minimum
altitude can damage the engine. For operation at
lower elevations, the standard main jet must be
used. Operating the engine with the wrong engine
configuration at a given altitude may increase
its emissions and decrease fuel efficiency and
performance.
WARNING
Operation at High Altitude
The density of air at high altitude is lower than at sea
level. Engine power is reduced as the air mass and air-
fuel ratio decrease. Engine power and generator output
will be reduced approximately 3½% for every 1000
feet of elevation above sea level. This is a natural trend
and cannot be changed by adjusting the engine. At high
altitudes increased exhaust emissions can also result
due to the increased enrichment of the air fuel ratio.
Other high altitude issues can include hard starting,
increased fuel consumption and spark plug fouling.
To alleviate high altitude issues other than the natural
power loss, Champion Power Equipment can provide a
high altitude carburetor main jet. The alternative main
jet and installation instructions can be obtained by
contacting Customer Support. Installation instructions
are also available in the Technical Bulletin area of the
Champion Power Equipment internet site.
The part number and recommended minimum altitude
for the application of the high altitude carburetor main
jet is listed in the table below.
In order to select the correct high altitude main jet
it is necessary to identify the carburetor model. For
this purpose, a code is stamped on the side of the
carburetor. Select the correct main jet part number
corresponding to the carburetor code found on your
particular carburetor.

Storage
For short and long-term storage, please follow these
guidelines.
Flushing the Pump
Flush the pump with clean water after each used is
advised. This will help to extend the life of the pump as
some materials pumped may leave residue that could
corrode parts, build up over time, or cause harm to any
plants, animals or humans. Flushing the pump will help
to reduce any damage and dangers caused by pumping
chemicals and pesticides.
Drain Plug
Make sure to unscrew and use the drain plug after each
use. By draining the pump, this will help to ensure little
to no water is left in the pump and will help prevent
damage to the pump if water residue freezes. DO NOT
use the Drain Plug during pump operation, as this may
cause injury or death.
Engine switch should be in the “OFF” position while pulling
the recoil cord, and performing storage maintenance steps.
NOTE
Engine Stored for Less than 30 Days
1. Allow the engine to cool completely before storage.
2. Clean engine according to the Maintenance section.
3. To extend the fuel storage life add a properly
formulated fuel stabilizer to the tank.
4. Ensure the fuel valve is in the “OFF” position.
Engine Stored for Over 30 Days
1. Add a properly formulated fuel stabilizer to the tank.
2. Run the engine for a few minutes so the treated fuel
cycles through the fuel system and carburetor.
3. Turn the fuel valve to the “Off” position.
4. Let the engine run until fuel starvation has stopped
the engine. This usually takes a few minutes.
5. The engine needs to cool completely before cleaning
and storage.
6. Clean the engine according to the maintenance section.
7. Change the oil.
8. Remove the spark plug and pour about 1⁄2 ounce
of oil into the cylinder. Crank the engine slowly to
distribute the oil and lubricate the cylinder.
9. Reattach the spark plug.

Chemical Pump Storage
1. Allow the chemical pump to cool completely before
storage.
2. Turn off the fuel supply at the fuel valve.
3. Drain the pump chamber thoroughly.
4. Clean the chemical pump according to the
instructions in the Maintenance section.
5. Store in a clean, dry place out of direct sunlight.
Winter Storage
Protect your chemical pump parts from freezing.
1. Apply all storage instructions from previous sections.
2. Make sure chemical pump hose is free of all water
before storing for winter.
Engine exhaust contains odorless and colourless
carbon monoxide gas.
To avoid accidental or unintended ignition of the
product during periods of storage, the following
precautions should be followed:
– When storing the chemical pump for short or
long periods of time make sure that the Engine
Switch and the Fuel Valve are set in the OFF
position.
DANGER
Our engines work well with 10% or less ethanol blend
fuels. When using blended fuels there are some issues
worth noting:
– Ethanol-gasoline blends can absorb more water than
gasoline alone.
– These blends can eventually separate, leaving water
or a watery goo in the tank, fuel valve and carburetor.
– With gravity-fed fuel supplies, this compromised fuel
can be drawn into the carburetor and cause damage
to the engine and/or potential hazards.
– There are only a few suppliers of fuel stabilizer that
are formulated to work with ethanol blend fuels.
– Any damages or hazards caused by using improper
fuel, improperly stored fuel, and/or improperly
formulated stabilizers, are not covered by
manufacture’s warranty.
It is advisable to always shut off the fuel supply, run the
engine to fuel starvation and drain the tank when the
equipment is not in use for more than 30 days.
